Available in PDF, EPUB and Kindle. Book excerpt: This paper reports first observations of the combustion properties of isolated boron/JP-10 slurry droplets in high temperature, atmospheric pressure oxidizing streams under low Reynolds number conditions. Slurry droplets of initial diameter between 400 and 500 micrometers and initial solid mass fraction of 0.3 were studied using single-lens reflex and high speed cine photography under both self illuminated and backlighted conditions. Boron slurry droplets burned for short periods of time with an envelope diffusion flame structure, but then experienced violent disruption for all cases studied. The intensity of the disruption progress was found to be strongly influenced by the temperature of the envelope diffusion flame. The ignition of the boron particles emitted from the initial fuel droplet was also affected by this flame temperature. As this flame temperature was increased by increasing the environmental oxygen content, the disruption occurred at earlier times in the vapor phase burning period. Ignition of the boron particles at high flame temperatures (> 2500K) was accompanied by a popping sound and a bright greenish flash of luminosity.

Book excerpt: Analytical and numerical studies on n-octane and aluminum metal slurry droplet combustion and metal slurry spray combustion are discussed. Two limiting isolated droplet configurations are studied: one with large metal particle enveloped by liquid hydrocarbon and another with many fine metal particles inside a liquid drop. Vaporization models for isolated slurry droplets are formulated which can be used in spray combustion calculations. An analytical model describes the combustion of aluminum particles in air. The particle transient heating, the phase-equilibrium conditions of the vapor and condensed products are analyzed. Mass and energy interactions between the slurry droplets and gas flow are studied in an idealized configuration consisting of parallel droplet streams. Without forced convection and preheat of the ambient air to temperatures near the aluminum oxide melting point, the flame does not possess sufficient energy to ignite the metal. Ignition times for the metal particle depend on the solid mass loading and can be several times larger than the liquid fuel burnout time. With many fine metal particles which are initially uniformly distributed in a liquid fuel droplet, depending on the shell characteristics different modes of liquid vaporization from the droplet can occur. At different combustor locations, interacting and distinct premixed and diffusion type reaction zones are present. The heating and burning times of the metal agglomerate are much larger than the liquid fuel vaporization times and increase with increasing metal particle size and metal loading of the droplets. Metal slurry vaporization; metal slurry combustion; aluminum particle combustion; aluminum particle burning; slurry droplets and sprays.
